eh... not for me.
I'm torn right now... I like the easiness of the Coralife and the fact that it would have everything built in. I don't like that it uses a magnetic ballast (according to Marine Depot customer support). I love my current setup because I have a nice transition... lunar to actnics to regular PC.
Here's the options
Separate: Buy two of the IceCap Spider Reflector with 250W 14k Hamilton Bulb and their electronic ballast. Estimated costs would be ~$750. The width is about 13" so I'll have roughly 6" of ceiling real estate. Find actinic lighting strip, etc that's about 3" wide to go on either side of the MH. Then space out actinic. Then space out the lunar lights. I have no idea how much actinics costs... lets say $200 for both lights.
Just MH & Lunar: Buy two of the IceCap Spider Reflector with 250W 14k Hamilton Bulb and their electronic ballast. Estimated costs would be ~$750. Downfall: no transition. Missing out on the actinics.
Coralife: $950. Has all the components. Not piece mealing it together. Magnetic ballast so monthly costs could be higher than above two. How much more? I don't know.
Right now... I'm with Jason... the Coralife seems to offer everything I'm really looking for. The only thing I'm scared about is the monthly costs.
When I think about magnetic ballast... I think about this article.
